lorder —
list dependencies for object files
The lorder utility uses
nm(1) to determine interdependencies
in the list of object files specified on the command line.
lorder outputs a list of file names where the first
file contains a symbol which is defined by the second file.
The output is normally used with
tsort(1) when a library is
created to determine the optimum ordering of the object modules so that all
references may be resolved in a single pass of the loader.
